PURPOSE:To save the trouble of sharing a charge by charging a line use rate to a sales-side even if a customer-side makes a call. CONSTITUTION:When the identification number of a side who takes the charge of the rate is previously registered in a number registration part 1 and the customer-side makes the call even if the customer-side makes the call, a number identification part 2 receives information through a public line, compares it with the identification number and sends a command which is called after cut with the identification number to a line connection part 3 when the numbers coincide so as to connect the customer-side. Sound is transmitted and received in a sound transmission/reception part 4 and a picture transmission part 5 transmits a picture. A picture display part 6 receives and displays the picture and a video conference is held. Thus, the sales-side can always take charge of the rate and the trouble can be saved. |
